SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 627,149, dated June 20,1899;

Applioationfiled June 28, 1897. Serial No- 642,6 94. (No model.)

To aZZ whom it may concern:

Be it known that I, CoLoMAN STEFAN, a sub ject of the Emperor ofAustria-Hungary, re siding at Vienna, in the Province of Lower Austria,in the Empire of Austria-Hungary,

have invented certain new and useful Improvements in Safety-Locks, (forwhich Letters Patent have been granted in Austria, dated June 24, 1896,registered Vol. XLVI, Fol. 2,547; in Hungary,dated May 31,1896,No.6,784; in Germany, dated March 31, 1896, No. 90,140; in France, datedJuly 24, 1896, No. 258,339, and in England, No. 14,029, dated June 8,1897, accepted August 7, 1897;) and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being bad to the accompanying drawings, and toletters and figures of reference marked thereon, which form a part ofthis specification.

This invention has relation to seal-locks; and it has for its object theprovision of means whereby the opening of the seal-box and theprojecting therefrom of the seal-holder are effected by key-operatedappliances when the locking-bolt is withdrawn from its keeper andwhereby the seal-holder is automatically returned into its box and thelatter closed when said bolt moves into engagement with its keeper. 7

The invention has for its further object the provision of means wherebyon the withdrawal of the locking-bolt from its keeper and therethroughthe opening of the'seal-box and the projection therefrom of theseal-holder the seal is simultaneously mutilated.

In the accompanyingdrawings I have shown myimproved seal-lockconstructed for use on railway-cars, the lock-bolt instead of engagingan ordinary keeper engaging a locking-lever, which latter engages akeeper on the body of the car when the lock is secured to a 3 is a viewsimilar to Fig. 1, the seal-box be ing shown in vertical section and apart of the locking-lever in dotted lines. Fig. 4 is a verticalcross-section taken about on line cc of Fig. 1. Fig. 5 is a rearelevation of the lock, the rear plate being removed and. show ing themechanisms in their positions when the bolt is in engagement with thelocking lever. Fig. 6 is a longitudinal sectional view taken about onthe irregular line a: 00 of Fig. 5. Fig. 7 is a view similar to Fig. 5,showing the mechanisms in their relative positions when the lock-boltisheld out of engagement with the locking-lever, which latter is shownas turned up, presumably out of engagement with its keeper. Fig. 5 is aperspective view of the rear end of the locking-lever. Fig. 9 shows by aface and edge view a mutilated seal, and Fig. 10 shows byaside and endview the key for the lock.

In Figs. 1 to 7 of the above-described figtires of the drawings, 0indicates the lockcase, to the front plate 0 of which is secured aseal-box B, that has a glass-faced opening I), the keyhole 1), adaptedto be closed by a guardplate b pivoted to the box B above the keyhole,and below said box the front plate a of the lock-case has a recess 0 forone of the fingers to facilitate the introduction of a seal into theseal holder or the removal of such seal therefrom. \V ithin theseal-boXB are two vertical parallel-grooved guide-ribs 19 in the groovesof which the seal-holder H has sliding motion.

The seal-holder II consists of a plate provided with overhanging edgeflanges h 011 three sides, forming a grooved framing for the receptionof the seal S, Fig. 9. On the guide stud or pin 29 for the key K, Fig.10, is secured a knife-holder 75, on which is formed or to which issecured a knife K, wedge-shaped or prismatic in cross-section. In theknifeholder 7c is formed a slot k in which lies a projection or lug .5-on the free end of a spring S, secured to the front plate 0 of thelock-case 0 within the seal-box B.

In the front plate 0 of the lock-case O and centrally between theparallel guides b for the seal-holder H is formed a vertical slot 0 andthe said seal-holder has in itslower edge a concave recess h tofacilitate the takinghold of the seal for its introduction into orremoval from the holder and on a line with the vertical slot 0 in thefront plate 0 of the lock-case 0 above referred to, and at its loweredge said seal-holder has a lug or shoulder h on its back (shown indotted lines in Fig. 3 and in full lines in Fig. 2) for locking theholder against motion in the sealbox, as hereinafter described, said lugor shoulder, together with a similar rib or shoulder 71, Fig. 2, servingalso to guide the seal-holder on the front plate 0 of the lock-case inproper position relatively to the vertical guides in the seal-box andthe knife, and from said projection h a stud or pin 71 extends throughthe vertical slot 0 above mentioned, for purposes presently to beexplained.

As shown in Fig. 3, the grooved guide 79 for the seal-holder H on theside of the key stud or pin 1) is cut away, as is also the grooved lframi ug on lhe seal-holder, so as to permit the knife when revolved bythe key to penetrate edgewise into the seal or controlling-card S andcut out a portion thereof, as shown in Fig. 9.

The open lower end of the seal-box B is closed by a gate G, hinged on apintle within the said box and provided with a lug or ear near itshinged connection, to which is pivoted one end of a link g, whoseopposite end is pivoted to the rear face of the seal-holder i H, asshown in dotted lines in Fig. 3, so that as said holder is raised orlowered, as hereinafter described, the gate G will he automaticallyopened or closed.

As hereinbefore stated, the keeper for the lock-bolt is a locking-leveradapted to engage a keeper of any suitable kind on a car. This lever Lis pivoted to the front plate 0 of the lock-case C through the medium ofa headed pivot-pin Z, screw-threaded at its inner end for a nut Z withinthelockcase 0, Figs. 5, 6, and 7. The rear end of the lever L isenlarged and made tapering outwardly, the rear edge being arcuate, theare having for center the axis of rotation of the pivot-pin Z, a similaroffset or shoulder Z being formed near said arcuate edge, which shouldermerges into a longitudinal recess Z The lock-bolt 2 has sliding motionwithin the lock-case on two pins 3, extending into slots in said bolt,the latter having at its forward end a locking-nose 4, formed at rightangles to the bolt and adapted to engage the recess Z in thelocking-lever L above referred to, said locking-nose projecting througha longitudinal slot a in the front plate 0 .of the lock-case 0, Fig. 6.A spring 5, acting upon a projection 2 from the bolt 2, holds the nose 4thereof in engagement with the recess Z at the rear end of thelocking-lever L. From the upper face of the lock-bolt 2 projects a whichnose when the seal-holder is in its normal position lies beneath theshoulder 71 of said holder, and thus looks it in position, as

more clearly shown in Fig. 2.

On the key stud or pin 13 is secured a boltactuating dog 8, so that whenthe key K is inserted into the keyhole its bit 7.2 will push the nose orlug s on the spring S out of the slot or notch in the knife-holder ande11- gage said slot, so that on turning the key in the proper directionthe dog 8 is likewise arm has bearing on a lever 12, provided with alongitudinal slot 12.

As hereinbefore stated, the seal-holder H has near its upper edge a bossor shoulder h ;from which projects a pin or stud 71 that ex- 1 tendsthrough a vertical slot 0 in the front f plate a of the lock-case, saidpin 72/ extending also into a slot 12 in lever 12, a spring S connectedwith the lock-bolt 2 and with said lever, tending to hold the same in anormal elevated position, Fig. 5, thus supporting the seal-holder H alsoin its normal position within the seal-box B.

To the lever 12 is pivoted a springcon- 2 trolled pawl P, adapted toengage the nose 7 on lever 7 when lever 12 is depressed in open- {ingthe lock.

The operation of the lock may be briefly described'as follows: The lockmechanism being in the position shown in Fig. 5, the seallbox B beingclosed and the seal-holder supported from the lever 12 and the nose 7 ofilever 7, said nose lying beneath the boss or Erib h on the back of theseal-holder H, as shown in Fig. 2, the key K being inserted .into thekeyhole and onto the guide-pin p the bit 70 on said key will push thelug or nose 8 on the spring S out of the slot k in the knife-holder 70.Upon turning the key in the the rear end of the locking-lever L, whichmay now be turned up from the position shown in Fig. 5 to the positionshown in Fig. 7, the offset or shoulder Z on said lever sliding alongthe locking-nose of the bolt 2 until said nose bears upon the upper edgeof said lever,where-' i by the bolt is held against forward movement. Asthe lock-bolt is drawn back the lever 7 is likewise drawn back, therebymoving its nose .7 from under the shoulder 71 on the sealholder H.

Simultaneously with these operations the longer arm of dog 8 acting uponthe shorter arm of angle-lever 10 causes the longer arm thereof todepress the lever 12 against the stress of its spring S and as thesealholder II is supported from said lever 12 and noW free to move downby, the withdrawal of the lock-nose 7 on lever 7 from under the shoulder71 on said holder the latter will also move down, and inasm uch as thegate G,which closes the lower end of the seal-box B,is linked to theholder H, the said gate is opened simultaneously, as shown in Fig. 3. Asthe lever 12 is about to reach the limit of its downward movement theinclined under face of the pawl P rides over the locking-nose 7 on lever7 and under the action of its spring said pawl engages the said nose,Fig. 7, thus locking the sealholder projecting from the open end of theseal-box against movement, so that the mutilated seal can be removed anda fresh seal introduced. It now the locking-lever L is turned down intoits operative position, Fig. 5, the bolt 2 will be projected by itsspiral spring 5 into the notch or recess 1 in said lever, and in thismovement of the bolt the lever 9 is tilted, thereby tilting dog 8 andreleasing leverlO. Atthesame timethelever7is moved forward, therebypushing aside the pawl P, so that under the action of the spring S onlever 12 the seal-holder is moved back into the seal-box and the gatethereof closed, while the nose '7 on lever 7 will have moved under theshoulder 7L2 on the back of'the seal-holder, thus again locking the samein position, the

knife-holder K being likewise returned to its normal position and willbe locked against motion by spring S.

From the relative arrangement of the levers 9 and 10 and dog 8 on thekey stud or pin 19 it will be readily seen that before said levers canbe acted upon by the dog it is necessary to impart to the latter abouthalf a revolution, so that the knife K, which is acted upon by the bitof the key, .has completed its out a little before or about the timesaid levers are acted upon by said dog 8.

It is obvious that a lock constructed as described cannot be tamperedwith without detection, since the bolt 2 cannot be moved out ofengagement with its keeper without at the same time turning the knife Kand mutilating the seal.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is
